The city's BioPark encompasses a zoo, an aquarium, botanic gardens and fishing ponds, spread out on either side of Central Avenue near the Rio Grande. For visitors, the gardens are the most interesting, as there are extensive displays on native desert plants, as well as the 10-acre Rio Grande Heritage Farm, where there are heirloom apple trees and Churro sheep. In the aquarium side, you’ll see a slightly dismal display on aquatic life of the Rio Grande before proceeding to the real crowd-pleasers: a tunnel full of creepy eels, lots of jellyfish and big shark tanks. The zoo is average, but a cute little train run between it and the aquarium, passing through Tingley Beach, a collection of fishing ponds where in summer you can also rent pedal boats or bicycles, if you want to cruise down the paved, flat Paseo del Bosque along the river.
